Re: [Matplotlib-users] Fail to allocate bitmap, Unable to free colormap, palette is still selected.
Chris Kennedy wrote:
hi Mike,
I was able to get it to work using:
reload(matplotlib)
matplotlib.use('Agg')
That suggests that the bug is somehow related to GUI code. As John
pointed out, we'll want to very exactly which GUI backend is being used.
I'll have to beat on it some more to see if this is robust.
I saw the error message in this code:
http://search.cpan.org/src/NI-S/Tk-804.027/pTk/mTk/win/tkWinDraw.c
if(!bitmap) {
panic(Fail to allocate bitmap\n);
DeleteDC(dcMem);
TkWinReleaseDrawableDC(d, dc, state);
return;
}
That seems to suggest that the TkAgg backend (or Tkinter itself) is
somehow the problem, assuming Gtk doesn't issue the same message (unlikely).
Thanks. Please let us know what other clues you can collect.
Cheers,
Mike

I don't see the string Fail to allocate bitmap or Unable to free
colormap... anywhere in the matplotlib source, so it's hard to say
where it's coming from. I suspect they are coming from the GUI
framework you are using...
If you put your simple example inside of a loop, does the error
eventually occur -- or only within the context of your app? If the
latter, we'll need to somehow narrow it down to a specific setting or
method that causes the problem.
Also, what backend are you using when it breaks? Just Agg, or one of
the Gui+Agg backends?

The code is simple:
import matplotlib
import matplotlib.pyplot as pylab
pylabFigure = pylab.figure()
pylabFigure.clf()
pylab.rcdefaults()
pylab.plot(p[0::2], p[1::2], 'b-', linewidth=3)
pylab.title('Endpointing Plot for '+StepMillName)
pylab.xlabel('Mill Distance ('+m_unit+')')
pylab.ylabel('~ Electron response ~' )
pylab.grid(True)
pylabFigure.savefig('EPP_'+StepMillName+'.png',
facecolor='lightgrey', edgecolor='w')
pylab.close('all')
pylabFigure = None
I can put this code in a simple program and generate many images
without seeing the allocate bitmap error.
Perhaps it is colliding with something else in my main app. Is there
a command that can clear, flush, or unselect the palette and/or
colormap?
I don't see the allocate error if I switch the backend to 'SVG', that
has it own set of issues though: telling me it can't use, but then
generating SVG files anyway.
thanks

[Matplotlib-users] Memory trouble with imshow
Dear all, I ran into a memory problem when trying to draw a few hundred png files using one imshow per file. The problem can be boiled down to the attached code which eats my memory very quickly until Python bombs out. I tried to del objects after their use, looked for garbage and read the user manual, but no luck. Did I do anything wrong or is this a memory leak? Cheers, Leif # discovered odd behaviour in relation to the imshow function # memory usage will go up quickly until the runtime breaks # watch it with the task manager # lxo, 19.02.2008 # running matplotlib-0.91.2.win32-py2.5.exe with wxPython 2.8.4.0 on Python 2.5.1 from pylab import * import gc for i in range (1000): A=rand(1024,1024) im = imshow(A) #del A #doesn't help #del im #doesn't help #print gc.garbage # no garbage This message has been checked for viruses but the contents of an attachment may still contain software viruses, which could damage your computer system: you are advised to perform your own checks.

I want pylab to just choose them, just as it does for colors. Well, pylab does choose: it varies color and not the dash pattern in order to have distinct lines. I think what you are wanting is something like the following: have pylab/pyplot cycle automatically through a set of preset Line2D property combinations, when an axes plots multiple lines. I think the answer is: this is not available in the form you want. (Indeed, it is hard for me to imagine agreement on nice choices for multiple properties.) Of course you can do something like this:: from itertools import cycle mystyles = ['r+-', 'b.--', 'go-.'] #etc ax1styles = cycle( mystyles ) for x,y in data: ax1.plot(x, y, ax1styles.next()) Cheers, Alan Isaac - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Matplotlib-users] MatPlotLib + Py2exe, backend problems ...
With Stef's help, I was able to get pass the Matplotlib datafile not found problem in using py2exe and Matplotlib under Python 2.3 - but then ran into the same Tkinter not loaded problem like he did. After reading Stef's messages from this list, I downloaded the latest version of Matplotlib - only to find that Python 2.3 is no longer supported. So, I loaded up Python 2.5 and ran the setup script for Py2exe. Now, py2exe is unable to find wxmsw26uh_vc.dll - eventhough I have wxPython 2.8 installed. So, I dug up a copy of wxPython 2.6 and have that installed. The file is now there but py2exe still can't find it. This is very fustrating!

This won't have the setup.cfg file, since it is a file that is used to configure the compilation process of matplotlib. Also this is why you can only use this distribution with specific versions of python, wx etc. If you choose to compile matplotlib yourself, then you have the option of completely disabling some of the backends, which is done via a setting in the setup.cfg file. I am not sure how easy it is to build matplotlib on windows, but on other platforms it is relatively straightforward. After obtaining the source distribution, ensure you have the requirements (including any development files) for the backends you want. Select the backends to build in setup.cfg and run python setup.py build followed by python setup.py install Hope this at least clears up the missing setup.cfg issue...

Re: [Matplotlib-users] MatPlotLib + Py2exe, backend problems ...
So, do I understand this correctly: In order to get rid of the Tkinter problem when building a matplotlib application using py2exe, I need 0.91.2 ver of matplotlib and use the setup.cfg file to select the backend I want (wxpython in my case). Then run py2exe to build the ap. Correct? But then, as I posted earlier, this create a new problem for me in that py2exe says it can't find wxmsw26uh_vc.dll - even though the file exists. What I need is a version of 0.91.2 ver of matplotlib that works with Python 2.3 to see if that works, or I guess I would include Tkinter with my exe?
